With what I heard in my system, it is pretty tough to beat the Bel Canto DAC2 I am currently using. I compared it to a more expensive dac. Yes, the more expensive dac was better, but it still did not make me want to sell the Bel Canto. I really was looking to hear big improvement and got dissapointed by a hair splitting differences. It wasn't worth it. Now back to Warren's point. I am thinking of moddig the DAC2. I think I can bridge that small gap between it and the performance of the more expensive dacs. Looking for a good modder, I am considering TRL. $550 that they charge for a mod is way less than the difference I need to pay to obtain a new dac that's going to beat the Bel Canto by a significant margin. So, point of dimishing returns for me in my system started at around the performance of a $1000 dac. May be my system is not revealing enough, but I have doubts about that.
